' This invention relates to certain improvements in gate operating and lockinginechanisms, and has relation moreparticuularly to a" mechanism of this general characterespecially designed andadapted foruse in connection with double doors, and it is an ob ject of the invention to provide such {LIIIBCllL-I nisrn having novel and improved means whereby the doorsv may be caused to: operate 10 in unison together with means for efi'ectively holding or'looking said doors when either in open or closed position, particularlyexplained. V v Fig; 1, is a plan view otmyiiinvent on showingthe doors lockedclosedgand showing partoifthe doorf-rame in section. -Fig. 2, 1s

a view similar to Fig. 1, but showing the doorslocked open. 7 tion on the line 33,7Fig. 1. Fig. 4:,1s an elevation of the inner side of one of the doors showing how the door handle is con nected with the lock-operating means. Fig,

of the handle for the door, in side elevation, and Fig. 7, isa detail showing how the guidebar for the latch carriage, is supported.

In the drawings, like letters of reference refer to the same parts. 7 r

The door-frame 2, may be of any desired construction, and suitably hinged thereto are the doors 3, which preferably open outwardly. 4c, is the guide-bar, and the same may be supported in any suitable manner I have shown its inner end attached to, part of the door-frame 2, and its outer endisattached to any suitable part of the bullding, such as a scantling 5; longitudinally on the guide-bar 451s a carriage 6, to which is pivoted the latch 7, as by means of the stud or pin 8. (See F1g. 3.) This latch is provided with upper side flanges I 9, which ride upon the said guide-bar, andat one end on its lower side it is provided with flanges 10 which engage thelunder side of said guide-bar. These flanges keep the said-can riage in cooperative relationship with said Fig. 3, is a cross sec.

Mounted to move guide-bar and permit of'the freedom oflnovemerit to said carriage 'But it must be understood thatl do not confine myself to any 3 function asIdesire. z i v Integrallyiormed with each side of the carriage 6, are ears 11, inlwhich are s'upported the inner ends of the thrust-rods 12. The outer ends oithese thrust-rods areinovably coupled to the fdoors 3, as by screw-eyes 13,

or equivalent means; i InfFig/l, the 'notch 15, of the latch 7, isshown ingenga'gement' withthe pin 14, car'-. ri'ed by'the guide bar" 4;ythis pin is located specific construction of. carriage that will v -17:

at' the limitof the inwardmoven ent of f-the 5 1'? j carriage'6', and wheirthe saidnotch 15, is in; engagement therewith, the carriage 6', is locked, and consequently the; doors" 3, are

' lo'c'kdr To unlock the said carriage from the guide-b-ar-Q, thelatchf7, is moved on itspivot pin or stud '8 to move the-notch 15, out of engagement with the pin 14; The

said' latch' must beheld lIltlIlS position so as to-allow the carriageto be moved outwardly. 'While 'Ifmay use any suitable 757.-

means to move the said latch as described, I prefer to use the following means, because thereby-I am enabled to dispense with the ordinary locking means now' almost universally used andlwhich consists of two memhers, one being carried by one door, and the Y other by the other'door. Mounted by means of a spindle 16, in one of therdoo'rs, are the members of the door handle, 17 and 18. These, members may be of: any suitable form orfshapebut I prefer-'to form them so that the hand-willenter same,as shown. -Carried by themember 18, is an ear 19,'to which one end of the fleXiblemembenQO, is connectedw This flexible "member"is passed through an eyelet 21, car ried'by one of the doors,;and its inner end is attached to the tail 22, of the latch 'Z. l Whenthe member 18, is turned on its jspindle 16, i the flexible m'emberQO, is-moved- -so as to retract the While the. member 18, is held in its: turned 7 position, the operatorpulls on same thereby moving the carriage 6 outwardlywalong the guidenotch from engagement with the pini l l.

ar 4.: Thismoveme'nt of the said carriage will cause the thrust-rods 12, to exert pressure against the doors and cause them to open. \Vhen the doors are fully open, the carriage 6 will contact with the pin 23, carried by the guide-bar, and when the turning force exerted by the hand against the member 18, is removed, the spring 24, will move the latch 7, back to normal position at which time the notch 25, of the said latch will engage with the pin 23, and so hold the doors locked in open position.

The member 18, is on the inside of its associated door, while the member 17 is on the outside. Since these members are connected together by the spindle 16, the move ment of one is the same as the movement of the other. When the doors are to be closed, naturally the hand grasps the member 17, and by turning same the latch 7 is disengaged from the pin23, and as pushing pressure isapplied to one of the doors, the said latch is ultimately caused to engage with the pin 14, and so look the doors closed.

Carried by the door supporting the mem bers 17, and 18, is an eye 26, with which matches an ear 27, carried by the member 17; this eye limits the movement of the members 17, and 18, in one direction so as to prevent any overthrow to the latch 7, which would cause its disengagement with the pins 14, and 23. v

Carried by the stud orpin 8, at one end, is the spring 24. As shown, this spring is coiled around said stud or pin, and the other end is placed to rest against the tail 22, of the latch 7. Energy stored in the said spring will move the said latch when this latter is not dominated by force exerted by the flexible member 20.

A stop 28, preferably formed by bending down portion of the latch 7 must be [provided; this stop comes in contact with the side of the carriage 6, (see Figs. 1, and 2'),

and so limits the movement given the said.

latch under the influence of the'spring 24-. The result is that the necessary movements can be given the said latch by the members 17, and 18.

A padlock, for instance, may be associated with the ear 27, and eye 26 so as to positively.

said carriage; an integrally formed springcontrolled horizontally disposed lat-ch member pivoted to said carriage to normally occupy a position longitudinally thereof and provided with oppositely faced hooks between which is located the pivotal point for said latch, and a stop carried by said latch for engagement with said carriage.

2. In a latching means as set forth in claim 1, the provision of top and bottom flanges for said carriage which have sliding contact with said bar.

3. In a latching means, the combination with. a horizontal bar, and a pin carried by each end of said bar and projecting above the top side thereof, of a latching means comprising a carriage adapted to be mounted on the said bar for longitudinal movement thereon; an integrally formed spring-controlled horizontally disposed latch member )iVOtGL'l to said carriage and provided with oppositely faced hooks between which is located the pivotal point for said latch; means for moving said carriage longitudinally on said bar to cause said hooks to alternately engage said pins; means for moving said latch so as to bring the engaged hook out of engagement with its associated pin, and a stop carried by said latch for engagement with said carriage.
